Having problems scanning my 2nd part
For my second part, i wanted to test an object with sharp edges and precise measurements, to be able then to measure the scanned dimensions .
But i'm running into trouble, i cannot get a clean scan, see pictures below.
The object is a metalic L shape bracket.
I tried various settings for brightness and level of details, i also tried with the object in different positions.
Any advice appreciated,

Powder it with talc it should then scan fine. if not you can also use spray paint primer.

Actually, it's not the scan that fails, but the alignment.
I can scan properly in free scan mode, the first scans comes out nicely, the second one as well, but when i ask the system to align them, this is where it starts to get ugly.
Advice on proper alignment would be really needed here.Last edited by Hugues; 07-05-2015 at 02:47 PM.

Success !
Definitely overlapping at least 1/3 with the new scan area is helping a lot, as advised by Shining 3D in another thread.
I managed to free scan a part on my bike, about 400mm by 400mm, low or medium detail setting, i forgot to check, but not high setting.
I used around 20 scans maybe, it took me around 1 hour, most worked with automatic alignment, except for one tricky part on the left side, i had to manually align, but despite this the system did not manage to align the part, so i deleted that last scan and came back to this problematic area from another side.
And the dimensions are pretty good, measured 347 mm between 2 screws, reality is pretty much 347mm, +/- 0.5 mm maybe.
Cool ! scan can be seen here, 25 meg only stl file:

Now, one cool new function would be to be able to stop a scanning session, save it (in whatever internal format you use) then re-open it later and continue the scan. This way we could scan quite large parts, like my whole bike :-)Last edited by Hugues; 07-06-2015 at 03:00 PM.
